What does GooManager do to the system, and how can we undo it? Or should the phone just be wiped and odin flashed to 4.3?
That's a common problem. You can't install a custom recovery using GooManager. At best, if you're running MDK, you can use Loki to flash a custom recovery.
The best fix for your situation is to flash a stock ROM. At the very least, grab the recovery from the stock ROM and flash that.
My Android devices:
vzw Samsung Galaxy S4 stock MJ7, no longer rooted.
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
